NBFS NBFSM is a part of the Fabric Shortest Path First (FSPF) protocol that handles a neighboring or
adjacent switch’s finite state machine (FSM).
Input to the FSM changes the local switch from one state to another, based on specific events. For
example, when two switches are connected to each other using an interswitch link (ISL) cable, they
are in the Init state. After both switches receive HELLO messages, they move to the Database
Exchange state, and so on.
NBFSM states are Down (0), Init (1), Database Exchange (2), Database Acknowledge Wait (3),
Database Wait (4), and Full (5).
NS Indicates problems with the simple Name Server module.
NSM NSM error messages indicate problems with the Interface Management and VLAN Management
module of the Fabric OS.
ONMD ONMD error messages indicate problems with the Operation, Administration and Maintenance
module of the Fabric OS.
PDM Parity data manager (PDM) is a user-space daemon responsible for the replication of persistent
configuration files from the primary partition to the secondary partition and from the active CP blade
to the standby CP blade.
PDTR PDTR messages indicate panic dump trace files have been created.
PLAT PLAT messages indicate hardware problems.
PMGR A group of messages relating to logical switch creation, deletion, and configuration.
PORT PORT error messages refer to the front-end user ports on the switch. Front-end user ports are
directly accessible by users to connect end devices or connect to other switches.
PS The performance server daemon measures the amount of traffic between endpoints or traffic with
particular frame formats, such as SCSI frames, IP frames, and customer-defined frames.
PSWP The portswap feature and associated commands generate these error messages.
RAS Informational messages when first failure data capture (FFDC) events are logged to the FFDC log
and size or roll-over warning.
RCS The reliable commit service daemon generates log entries when it receives a request from the
zoning, security, or management server for passing data messages to switches in the fabric. RCS
then requests reliable transport write and read (RTWR) to deliver the message. RCS also acts as a
gatekeeper, limiting the number of outstanding requests for the Zoning, Security, or Management
Server modules.
RKD These messages are either error or informational messages pertaining to the re-key daemon of the
Fabric OS.
RMON RMON messages are error or informational messages pertaining to the RMOND daemon.
RPCD The remote procedure call daemon (RPCD) is used by Fabric Access for API-related tasks.
RTE RTE is responsible for determining the correct paths for each ingress frame and populating the
routing tables in the ASICs with this information. The ASIC then uses the information available in the
routing tables to determine the path a particular ingress frame needs to take before it exits the
switch.
RTWR The reliable transport write and read daemon helps deliver data messages either to specific
switches in the fabric or to all of the switches in the fabric. For example, if some of the switches are
not reachable or are offline, RTWR returns an “unreachable” message to the caller, allowing the
caller to take the appropriate action. If a switch is not responding, RTWR retries 100 times.
SCN The internal state change notification daemon is used for state change notifications from the kernel
to the daemons within Fabric OS.
